So I'm looking at the map and wineries and stuff, and I have a couple thoughts:

1. Christie Wineries would be on the way to Valley of the Moon (as would many other good Sonoma wineries)

2. In fact, there's a lot of good Sonoma wineries surrounding Valley of the Moon.

Do we want to do half of this event in Russian River, and half in Sonoma?

Personally, I would suggest that we do Sonoma a different year. Russian River and Dry Creek are worth their own Vintacon, and likewise Sonoma is definitely worth its own Vintacon. I think we shouldn't try to do both in the same weekend.
